Abstract

An underground digital locating system (10) includes a receiver (12) capable of acquiring a signal produced by an underground obj and displaying a digital representation of the orientation of underground object and of its depth. The system (10) includes a carrying case (U) for the digital locating receiver (12), the carrying case (14) further including a transmitter for energizing underground obje to emit a magnetic field. A method of locating an underground object using the described system (10) is also disclosed, as well as methods of measuring a flux field and translating a flux field signal of an underground object into a visual representation of the underground object on the display screen of the locating receiver (12).
